Celebrity socialite Paris Hilton has been banned from two Wynn resorts on the Las Vegas Strip and her boyfriend has been dismissed as nightclub manager following their arrests.

Wynn spokeswoman Jennifer Dunne said Wednesday that Hilton won't be allowed at the properties anymore.

Dunne says Cy Waits has been "separated" from his job as managing partner of the Tryst Nightclub at Wynn and XS The Nightclub at Encore.

Also today, a police officer reported finding a rolled paper "roach" that he believed was marijuana in a vehicle after Waits failed field sobriety tests during a traffic stop on the Las Vegas Strip.

Waits spent a night in jail on suspicion of misdemeanor driving under the influence.

He's free on $2,000 bail. A criminal case not yet been filed.

Hilton was arrested late Friday on a felony cocaine possession charge and Waits was arrested on suspicion of misdemeanor driving under the influence after police smelled marijuana coming from their vehicle.

Police say a bag containing 0.8 of a gram of cocaine fell out when Hilton reached into a purse for lip balm. She has an Oct. 27 court date.
